Hi,

what´s in the TMG logs?

How are your TMG NICs configured?

2 NICs: Internal & External. DNS configured on internal nic. Default gateway on external nic.
Internal nic bound to all protocols/clients except NLB. External NIC bound to all protocols/clients, except MS Client, File & Print Client & NLB.
